Dose capture device for syringes

Abstract

Described herein is a smart dose monitoring device. The dose monitoring device may include electronics such as motion sensors, orientation sensors, and timers related to monitoring the time of and amount of dose administered during an injection event.

Description

RELATED U.S. APPLICATIONS[0001]This application claims priority to U.S. Provisional Appl. No. 62 / 107,946 filed on Jan. 26, 2015, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to syringes, and more particularly, relates to smart devices for capturing dosing data from syringes.[0004]2. Description of the Related Art[0005]There are multiple diseases wherein patients have an active role in disease management. Under some treatment regimens, a patient may be required to inject medicament into their body multiple times per day. For example, diabetic patients must self-inject insulin in order to control blood sugar levels. When preparing to self-inject medicament, a patient may need to take several factors into account. For example, a patient may need to keep track of previous injection dose amounts as well as the precise times at which those doses were administered in order to calculate the do...

AI Technical Summary

Benefits of technology

[0009]Another embodiment of the present invention is a method for calculating and recording the dose amount and the precise time of previous medicament injections. The method may include providing a syringe having a plunger configured to administer a medicament, providing a dose monitoring device comprising one or more motion sensors, one or more orientation sensors, and a timer, wherein the dose monitoring device attaches to the syringe and is configured to detect data using the one or more motion sensors, the one or more orientation sensors, and the timer, transmitting the data to a processor, and determining which data corresponds to an injection event of the syringe.

Problems solved by technology

It can prove difficult for a patient to keep track of the dose amount and time of each injection event.

Furthermore, after extracting insulin into a syringe, but before injection into a patient, some medicament may be lost from the syringe during “priming,” the removal of air bubbles from the syringe.

This may cause the patient to incorrectly remember the amount of insulin that was originally drawn into the syringe as the injected dose amount.

These issues create a possibility of error in determining dose amounts and times which are used for subsequent self-injections.

The multiple motions of the plunger prior to injection may all be recorded and lead to erroneous measurements of the distance traveled by the plunger during injection, and consequently of the dose amount.
